I've been beta testing GBTimelapse' upcoming AutoRamp feature by doing sunset and overnight shots of the sky. Last weekend while on a ski trip to Kirkwood in Northern California, I pointed my Canon T2i at the sky outside of the condo window. I expected to get a good clip of a black sky with the stars rotating around Polaris, but instead the sky was bright blue in the middle of the night....
You need to watch in HD to see the stars
.. I had forgotten about the nearly full moon. The light from the moon lit up the hillside so brightly, it looks like the middle of the day.
I wish the clip went on longer, but there was a power failure at 3AM that shut down my netbook computer and the camera.
